Aim:To find out the relationship between the height of a ball is dropped from,and height of the balls first bounce

Hypothesis:I predicted that when the ball dropped it'll be high

Method:Stand on the Table and then use two rulers to measure.We used Johannas phone to to see the measurement accurately and used a calculator to see the averages.

Results:The ball went up high and the Averages was

3: 95.5

2: 71.3

1: 41.3

0.5: 21.3

(Graph in my book.)

Discussion: When we dropped the ball on a high surface and the ball bounced high.The highest was drop height 3

Conclusion:I agree with my Hyphothesis
